[jboss-user] [EJB 3.0] - why Ejb cant invoke destroy method?

Monday, 12 February 2007

Hello

I am using JBoss Seam 1.1.6 GA and Apache Tomcat 5.5.17 and Seam is using embedded Ejb in
tomcat.

I have one Stateful and one conversational bean in my project.
sometimes the Seam can not invoke the destroy() method and throws an exception. this
exception can been seen on tomcat console with following message:

it's wondering me why this happen sometimes not always!
I have declared this method in the local interface and marked them with @Remove and
@Destroy in its implementation class.

also, I handled any exception might be happen in destroy method by putting try/catch
statement.

I asked this question in Seam's forum and Gavin refer me to this forum. as he states
it is a bug in Ejb3 and Ejb throws NPE back to me.

thanks
